Solid and Firm, but not too Firm
Size: Standard (Pack of 1)
Great pillow, best I ever put my head against!
Not too high, not too firm, do not recommend for stomach sleepers, but I am mostly a back sleeper. It is also heavy enough to support your head.

⭐️⭐️⭐️⭐️ Adjustable and Better Than Most I’ve Tried
Size: Standard (Pack of 1)
I’m a really tough pillow critic and have a hard time finding one I actually like. With that said, this pillow was better than a lot of others I’ve tried—mainly because you can remove some of the latex shavings to adjust the firmness. I ended up taking out about 20% (do it over a big trash can because the shavings can get messy!).
When it arrived it was too firm for me, which is why I had to take some filling out. Even after adjusting it, it’s still not my absolute favorite pillow, but I do use it every night as a “hug” pillow and it works great for that. I think people who aren’t as picky as I am will probably really enjoy it, especially since you can customize the amount of latex to get it just right.
I’d give it 3.5 stars, but rounded up to 4.

Great size for vintage pillowcases
Size: Standard (Pack of 1)
Gives good support. And very pleased w/ comfort. Slightly larger than old replacement, but not the over-sized "standard" of 25".

Dream pillow
I’ve been using latex pillows for over 30 years, and I can’t find them in local stores anymore. I’ve been needing to replace my pillow and finally decided to try this one. There are so many options on Amazon that it’s overwhelming. But this standard low loft pillow ended up being PERFECT. It feels amazing and just like the pillows I’ve been using since childhood. It is soft but cradles my head and neck perfectly. For me, it’s like sleeping on a gentle cloud. Very happy with my purchase. (Yes, it does have a slight latex odor. That is normal due to the material. It’s not very strong and it doesn’t bother me).
